INCUBATOR'.

SPECIFICATION forming part of Letters Patent N o. 7 18,47 9, dated January 1 3, 1903.

Application filed October 17,1901. Serial No. 79,046. (No niodelf)- T0 1f/ZZ whom it rita/y concern;

Beit knownthat I, FREDERICK C. KECK, a

citizen of the United States, residing at Joy,` inthe county of Mercer and State ot' Illinois,

have invented a new and useful Improvexnent in Incubators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertai'ns to make and use the same.

The invention relates to improvements in incubators; and it has for its object to provide simple' and efficient means for supplying moist air to incubators without the employment of pans of water or similar means arranged Within or adjacent to the egg-compartment, whereby the air within the incubator is prevented from becoming too heavily laden and overcharged with moisture, thereby preventing sweating of the eggs and the bad eects resulting therefrom.

The invention consistsin the novel construction andarrangement of parts hereinafter described and shown, and particularly pointed out in the claims hereto appended.

In the drawings forming partof this specification, and in which like numerals of reference designate corresponding parts, Figure l is a vertical sectional view, partly in ele.va-.

tion, of an incubatorconstructed in accordance with this invention.4 Fig. 2 is a detail sectional view illustrating the construction of the sleeve to which the pipe or conduit is connected.

Referring to the drawings, l designates a sleeve surrounding a hot-air line 2 of an incubator 3 and provided at one side with a nipple 4, to which is connected a hose 5. The sleeve which surrounds and is spaced from the hot-air viiue 2 to provide an. intervening annular passage 6 is closed at its lower end by an annular flange 7, L-shaped in cross-section and secured to the hot-air flue 2, as clearly shown in Fig. 2 of the drawings. The incubator-may be of any desired construction, and the hot-air iiue is designed to receive the chimney of a lamp or any other suitable form of heater.

lThe incubator is designed to be arranged in a room or apartment above the ground and containing dry warm air, and the pipe or conduit 5, which preferably consists of rubber hose, extends outward and downward from the iiue and the outer sleeve or casing l becomes heated and ascends into the incubator, thereby causing a circulation of moist air through the pipe or conduit. By this means the incubator is supplied with moist air sufficient'for the purposes of incubation, and the air within the incubator is thereby prevented froin becoming overcharged with moisture, as is the case when the Warm air in the incubator on entering the incubator is per- -mitted to come directly in contact with a body of water, as is the case where water-pans or similar receptacles are employed. By these means the eggs are prevented fromsweating and the incubation is not retarded and interfered with, as is the case when the eggs become damp by deposits of moisture on them.

The pipe or conduit may be connected with the incubator and with a well or cistern in any other desired manner, and I desire it vto be understood that these and similar changes may be made without departing from the spirit or sacriiicin g any advantagesfof the invention.

What I claim isl. Ina device of the class described, the combination of van incubator, a heater, a source of supply of cold moist air provided with a body of water arranged at a point suficiently remote Vfrom the heater to prevent thewaterpfrom being heated by the same whereby the supply of cold moist air to the incubator will be continuous, and a pipe or Yconduit extending from the source of supply and'discharging into the incubator adjacent to the heater, substantially as described.

2. In a device of the class described, the combination with an incubator, and a source of supply of-1noist air arranged at a point remote .from the incubator, of a hot-air iiue communicating with the incubator, a sleeve' In testimony whereof I have signed my o1' casing surrounding the flue and closed at name to this specication in presence of two the bottom and communicating at the lLop subscribing Witnesses.

with the interior of theinoubator, and a pipe FREDERICK C. KECK. o1' conduit extending from the sleeve or cas- Witnesses: ing to the source of supply of moist air, sub- PAUL BUSTARD,

stantially as described. JACOB G. STALEY.
